Lung infection back among Covid positive elderly

A cursory analysis of nearly 200 Covid-19 patients hospitalised across the state's medical colleges underlines this observation among physicians. Doctors have primarily seen Omicron cause upper respiratory tract infections, including sore throat, runny nose, irritation and swelling of the throat. "But lately, the infection appears to have travelled to the lungs in some patients," said a state official. "While it has not caused any notable rise in deaths, patients requiring oxygen have seen a marginal rise," he added.
